Ensoniq dsk-8 manual

When using the Mirage in stereo, connect this jack to one channel of your mixer and pan that channel left. Page 37 The digits 0 through 9 represent themselves. Comments to this Manuals Your Name. Sampling SAMPLING Sampling your own sounds with the Mirage is where the fun really begins, Just about any sound can be a source of inspiration for you, since just about any sound can be recorded esoniq processed with the Mirage.

Sign In Sign Up. Attack, Decay, Sustain, Release. Page 27 Once you have finished using the Formatting Program and wish to return to Once you have finished using the Formatting Program and wish to return to normal operation, normal operation, you can reboot the Mirage from a standard sound diskette without turning the machine mirafe. Just the reverse process! I seem to recall this works! This website uses cookies to improve your experience while you navigate through the website.

The two in the back by external filter plug are NOT stuck down to case but to a sheet of cardboard? I replaced bad socket for voice 3. Pin in socket was bent so it was super loose. Replacing did not fix voice problem but did get rid of 10v readings I had been seeing. I trace signals back to U59 a responsible for voice 3 cutoff frequency and it is reading mv all the time while all others read around 5mv.

Not normal. I have a and nice new dual-wiper sockets. Time to replace U Job complete and voice 3 is back working! Tool Tip. One key is bad- G3 retriggers and even causes the LED to flicker off and on sometimes.

But it plays. F4 wiggles all on its own when playing. Need to look for any signs of broken or loose parts. I took it apart and fixed it. Not sure how. I did bend the part the hold the main part of key in place ever so slightly. White needs to come out before black they block removal.

The white keys are labeled underneath- I think each key for a given note is interchangeable in any octave. Two sensor strips under the keys- long, continuous strips for easy of holding them down. Little plastic nipples on the bottom of the stips poke through board under the keys. Strip looks very standard, like on a Blofeld.

I will need to try and lift the strip around G3 and clean the contacts. G3 is good but now G3 and A4 are bad. All the diodes are good my multimeter has a diode test mode- yours should too since useful to test transistors, as well. Velocity sensitivity is working. All keys trigger. Looking down over the board, the edge of cable towards center of the pcb aligns with the edge of the header.

That leaves at few a little overhang 2 or 4 sockets at edge by top of pcb. Made by American Keyboard Company. Syntaur has a ton of Mirage parts. You have to use an old style floppy with a 34 pin connection. Reason is you need to access low level drivers and USB prevents that. The smart guys behind Omniflop can explain that, so read on. I tried to write a Mirage disk with the mwrite tool, which is supposed to write ensoniq disk images to a mirage-formatted floppy. It fails at trying to write.

At least it tries. Unclear why it fails- old floppy drives could be part of the problem. I cleaned the inside- especially the heads that read the disk. Like a tape head they can get magnetic oxide on them. I am kind of suspicious that the power plug to the floppy was not installed right, but it is now. By the way, you can create an old Windows 98 or similar VM and run inside VirtualBox; however, getting access to peripherals, browsing the web, etc.

Maybe I could have fought my way through, but simpler to use a fully-working old PC. Omniflop is THE answer when working with old floppy drives.

Genius product idea. I installed the bit version on my vintage computer. Then my floppy became super powered and went from handling 28 formats normal to ! They all work and soundprocess turns the Mirage into a great sounding polyphonic digital synth with analog filters, no less. A single floppy for Soundprocess holds 3 banks of 32 sounds each — pretty remarkable. What disks to use with a Mirage? DD- double density. I am an engineer and I like real answers on technology.

There are those who say you cannot use HD floppies on the Mirage or with Omniflop, but that is not true as I have been doing it. So what is the ground truth? I went looking and found high density HD media will work but there are risks described below.

I also found that extra hole has nothing to do with being double-sided or not; it is if HD or not! You cannot use DD diskettes reliably under high density HD formatting and use; typically they will fail format. While HD diskettes will format as DD, they will not likely hold the data reliably.

Read the double-density notes above for more details and some terminology. High density disks use a different formulation of oxide with a higher coercivity which means that it takes more magnetic force to properly magnetize the oxide. When a disk is used in high density mode the drive makes the adjustment to the driver circuits.

If you fake the drive out by taping over the [HD disk identifying] hole [to use HD disks at DD] it uses the lower magnetic force required for the double density discs.

This can lead to higher error rates and the data just disappearing. I asked Chuck Guzis, formerly of Sydex Inc and a data recovery specialist, for his experience and views. I needed this to read manuals and such. Took me 4 tries to find a simple, downloadable PDF reader that just work. Nothing to install, just run when needed.

U56 pin 7 output shows more voltage if I hit keys harder velocity and hit more keys. That is good. If a CEM is bad, I already found a provider on www. The keyboard will NOT work right unless screwed in. I think it is related to grounding. Soundprocess OS- this turns the Mirage into an 8 voice 4 oscillator digital synth with analog filters. This also shows how to use a linux tool called superformat to create a Mirage formatted disk without needing the special formatter disk.

May want model in a case. These instructions use Omniflop for step 1- you need a non-USB floppy drive in order to dump a mirage disk and get the image you rename in step two. Note: if you want to swap between emulator and floppy, you can write from the Mirage to the floppy, making new Mirage disks! Just tedious. However, the disk only contains data on one side of the disk with 80 tracks numbered 0 — Like the SQ, each track has five byte sectors numbered consecutively from zero to four followed by one sector of bytes with a sector ID of five.

The following examples should clarify this. The diskette may contain the Operating System, six sounds configured as 3 lower-half keyboard sounds and 3 upper-half keyboard sounds and either eight short sequences or three long sequences.

The remaining 5k of the Operating System is stored only on small sectors Sector 5 from Track 2 to Track The configuration parameters are stored on Track 11, Sector 5.

The directory and the sequences are only stored on the small sectors Sector 5 and the sound files are only stored on the large sectors Sectors Mirage Directory Sectors The directory information for the Mirage is contained in three bytes which are stored in three sectors of the diskette.

Each sector contains copies of the directory byte for that sector. Therefore, the Mirage would read or write the sector and would use the last byte of the sector as the valid value for the directory byte.

Track 32, Sector 5 contains the Sound Directory Byte. The directory bytes are de- fined as follows:. If the Sound or Sequence exists, the appropriate bit is set to one 1.

If not, the bit is cleared 0. As the various formats suggest, Ensoniq has come a long way since the Mirage single-sided drives. I would like to suggest that they consider the possibility of using the higher density 1. The drives and diskettes are not that much more expensive, but they would make a big difference especially with the EPS The lower density diskettes could still be used with the higher density drives giving us the option of which diskettes we want to buy.

If new formats are introduced, I will try to include their formats in future issues of the Hacker. If you have questions concerning the formats, please feel free to contact me.

If you have a disk you thought was forever lost, you may be able to recover the files using this information. Hey, I just wanted to thank you for documenting this. Like Like. I have proper floppy disks, many of the old files and I can transfer them with an old PC I set up just for this. Contact me at eizdepski at yahoo. I bought one without the noise reduction mod, and it has the 2. I think you will have to ask around to find someone who will burn one for you.

See schematic for more. I have never heard of a noise reduction mod. Thanks for providing this information! I have a first gen Mirage with a dead 4th voice. I have read the section here that discusses fixing your dead 3rd voice, but I am unclear of what exactly you did you get it working again. Page 20 The parameters of the Mirage are divided into two main categories-playback parameters and sampling parameters. Again, these are guidelines mrage you can set the values of these parameters to any values you want.

Here are a few general tips which will help you to make better quality samples Following are two tables — the first for the Ensoniq ESQ-1, the DX — 7 and any other instruments which begin program numbers at 1, and the next showing the There are no reviews to display. While in this digital form, the signal can be modified in many ways, without deteriorating the audio quality and without the mechanical limitations of tape recording.

At Ensoniq, many hours enspniq effort and a great deal of care go into creating the sounds provided on Ensoniq Sound Diskettes. The Display shows the new value of the internal clock rate.

Page 16 You can speed up or slow down the playback of the sequence by changing the value of parameter 87 see Selecting and Changing a Parameter. Sampling SAMPLING Sampling your own sounds with the Mirage is where the fun really begins, Just about any sound can be a source of inspiration for you, since just about any sound can be recorded and processed with the Mirage.

This manual is a simple and. When mannual than one wavesample is used, you must select the location in the memory for each wavesample.

Page 7 Diskettes have a sliding write-protection tab so that you can protect your own sounds and programs against accidental erasure.

An ever-growing library of manuaal is miragf from Ensoniq that will keep your Mirage fresh and new for years to come. Single Wavesample Wavetables Also, any sound you sample will be played back through the program presently selected. Sliding the tab so that the window is open will protect the diskette against over-writing and erasure.
